Pico Toning Duration and Aftercare Tips for Preventing Melasma Recurrence

I am considering picosecond-scale precision laser toning to treat melasma and freckles, which have been a long-standing concern for me. I sincerely hope that after the procedure brightens and evens out my dull skin tone, that clarity will last for a long time.

I would like to know how long the effects of Pico Toning typically last after the entire treatment process is completely finished. I am also wondering if any aftercare is necessary to extend the duration of the Pico Toning effect and prevent melasma from darkening again due to UV rays or irritation once treatment is stopped.

I await a professional response from the medical staff regarding the sun protection and moisturizing habits recommended by the hospital, as well as whether there are specific intervals for maintenance treatments after Pico Toning.
